TITAN 3C TRANSTAGE R/B, 9855
Orbit data source: Space-Track
TITAN 3C TRANSTAGE R/B, 9855 is space debris in GEO originally from a launch on Sun, 06 Feb 1977 UTC launched from the Air Force Eastern Test Range (AFETR). Debris objects in space refer to the collection of defunct objects orbiting the Earth. Examples of debris include non-operational satellites, rocket bodies, and fragments generated from explosions, collisions, or faulty payload assembly.
